Hi everyone,
I am currently coding a simple Data Access Layer, and I was wondering which type I should expose to the other layers.
I am going to internally implement the Data as a List<>, but I remember reading something about not exposing the List...

IList is good, but sometimes you may need ICollection....
Which interface depends on the circumstances.
Using an interface will reduce coupling and make it easier to change details of your data layer's implementation down the road .
Definitely an ISomething.

Hi, we're considering exposing some C# types to C++ clients via COM. What problems can we expect to hit over the life of the project? E.g. how will versioning be managed?
On versioning, it would seem from reading this that we should decorate our types...

Dispatch interfaces are useful when using scripting clients such as VBS but they are rarely useful for C++ clients .
Since you are using a C++ client you should definitely use explicit interfaces for early binding .

I often come across web applications that expose internal database primary keys through forms like select boxes. And occasionally I see javascript matching against an int or guid magic value that switches the logic.

Not so with a generated key.
This is one instance where exposing a PK would "break" an app unrelated to the security of the app.
To that data would now point at a different set of data .

The two lines in your example amount to the same thing, but if you expose IList<T> as a property, you can change exactly what gets returned without....

I've heard that exposing database IDs (in URLs, for example) is a security risk, but I'm having trouble understanding why.
Any opinions or links on why it's a risk, or why it isn't?
EDIT: of course the access is scoped, e.g. if you can't see resource ...

Exposing the database ID counts the proper conditions, exposing identifiers is not a security risk.

I have some object classes that use inheritance. It seems that I can only get access to the objects that are directly used by a service. Let me show you what I am trying to accomplish:

It is always better to expose the minimal set of data required.
Then you shouldn't be exposing them.

I know I shouldn't be exposing a List<T> in a property, but I wonder what the proper way to do it is? For example, doing this:
